摘要(Abstract)：

应用323 K三元子体系的溶解度数据,采用多元线性回归方法拟合出该四元体系在323 K时的Pitzer方程的混合离子相互作用参数θ(Br-,SO24-),Ψ(Na+,Br-,SO24-),Ψ(K+,Br-,SO24-)(相关文献鲜有报道),在此基础上应用Pitzer方程对323 K四元体系Na+,K+∥Br-,SO24--H2O的溶解度数据进行理论计算,并用计算出的溶解度数据绘制出四元相图。计算结果表明,模拟计算值与实测值基本吻合,较好地验证了实验数据的准确性,同时也表明含有合理参数的Pitzer模型完全可以描述含Na+,K+∥Br-,SO24--H2O的体系。
